Our DD slept through from 9.30pm through to 6am when she was 6 weeks old ... as soon as i started introducing a small feed before my bedtime she was fine and dropped her late feed soon thereafter .. she has not woken overnight for a feed since then ... i agree with PP Kafer_Girl that all babies are different ... in saying that though ... i have been to karitane with DD for sleep issues assoc with reflux and am a big believer in as they get older, sleep during the day promotes sleep at night ....
